R+=+m%5E2-95m-500
break even happens when R=0
+m%5E2-95m-500=0....factor
+m%5E2%2B5m-100m-500=0
+%28m%5E2%2B5m%29-%28100m%2B500%29=0
+m%28m%2B5%29-100%28m%2B5%29=0
%28x+-100%29%28x+%2B+5%29=0
need only positive solution

x=100

answer: 100 liters of the acid solution should it manufacture to break even
